i have schizo bindings which are basically demo bindings but you can move the pieces up and down the ski and keep the same bsl. I don’t like them but I suck at park and can still slide rails perfectly fine.

idk shit about binding tech, but I had demo bindings when I learned how to ski rails and I survived. Weight could be an issue, but I think the solution here is to call him a pussy until he decides to quit skiing forever.

I mean, they are a little heavier but not heavy enough to make someone "suck at rails". Ur friend is making an excuse

However, demo bindings are kinda sketchy reliability-wise compared to normal alpine bindings. So easy to come out of em when you don't want to. Wouldn't want to be pushing it too hard on a pair of demos.
